!$ Makita BDF452 18 Volt LXT Lithium Ion Cordless 1 2 Inch Driver Drill Kit



I bought one of these drill kits several years ago and used it a lot the first year as it was the only lithium-ion powered drill I could find and I loved the LED light which was a unique feature at that time. I was using it in place of a lightweight 3/8" cord drill and a Milwaukee 18 volt NiCad drill and the Makita was a big improvement over both. Since that time I have bought more than a dozen cordless drills for my business and almost all with lithium-ion batteries. When you can compare multiple drills with the same hole saws or screw driving work it becomes evident the strengths and weaknesses of each.



There is a very human tendency to personalize a purchase decision and identify with a product whether it is a make of car or a brand of soft drink or a power tool. I hear people say that Makita is the best or Milwaukee or DeWalt and I know they are not really credible as they have limited experience and a closed mind.



Makita definitely makes a good lightweight cordless drill but so do Ridgid, Milwaukee, Hitachi, and DeWalt. If you have a bunch of DeWalt or Makita batteries around and need a new power tool it makes perfect sense to stay with that manufacturer everything else being equal. But I have found big differences in real drill power and in chuck and gearbox performance between different brands and different models and Makita comes up in the middle of the pack with better performance and value from the drill kits made by DeWalt (DC760) and Milwaukee (2602).



The Makita chuck is not very good at gripping a hole cutter where there is any amount of vibration. The Makita positioning of the forward and reverse lever is too low and it is very easy to switch out of forward while depressing the trigger of the drill. This is not the case with the compact drills from Hitachi, Milwaukee, or DeWalt that I own and use, only the baby Makita BDF452. If you have small hands and never wear gloves this may not be a problem.



Makita batteries are charged quicker than most by the Makita charger but Makita also recommends in their charger guide that the batteries stay on the charger for an extra 30-60 minutes to cool down so total time is the same or longer than with other manufacturers' lithium-ion batteries.



The advantage of this version of the Makita BDF452 over the white model is the use of full size Makita batteries. This adds weight but also makes it possible to get the full power potential out of the drill. The 1.5 Ah batteries from Makita provide less than half the torque from the drill motor and quickly drain when cutting hard materials. This may not matter to you but it is something to consider before you buy as replacing the batteries from the white Makita kit is expensive.



Makita has a 1 year warranty on the batteries compared to 2 years with DeWalt. At the current price for replacement batteries any drill that is going to be used heavily will be cheaper to operate with the DeWalt drills and lithium-ion batteries.



As this is a 5 year old model it also has the 5 year old carry case that has lots of room for spare items but is pretty marginal at holding the batteries, even the half-size versions. Not a big deal but if you put a new Milwaukee drill case side by side with the Makita you will see that Milwaukee puts a lot more thought into the details (like the position of the forward-reverse switch).



For ultimate power I recommend the DeWalt DC760 18 volt drill that has lithium ion batteries that provide 20 volts of power. For a drill that performs well in every aspect I would not hesitate to buy the Milwaukee 2602 with the full size batteries so long as I did not care about possible shorter battery life and compatibility issues with new batteries in the future.



Regardless of which drill you buy the performance will be greatly improved if you keep the battery full charged after each use and are sure to use modern hole cutters and toss your bi-metal hole saws.
